Imijikelezo (spirals) ingenye yezinhlobo ezivame kakhulu emkhathini, ivela njalo emvelweni, ebucikweni, nakwezobuchwepheshe banamuhla. Kusukela ekugudlukeni okumangalisayo komthala kuya ekugoqekeni okuthambile kwegobolondo lenkumba (nautilus), umjikelezo uthumba umcabango wethu njengoba kungenza zimbalwa izimo. Ngenkathi ubona amaphethini ajikelezayo aqoshwe ezitsheni zasendulo noma uhlaba umxhwele ngemivini ekhula kahle egandaywe ensimini, ububona ubujyometri obuye bathakasa isintu iminyaka eyizinkulungwane. Amasiko aqhubeka nokukhulisa lokhu kuthakasela, kungaba kubuciko bephosta ejikelezayo yefilimu ka-1998 i-Spiral noma kungaba kusibonakaliso esesabekayo esimaka uchungechunge olusha lwe-Texas Chainsaw. Nokho, umjikelezo awuyona nje into enhle yokuhlobisa, ngoba uqukethe ubuhle bezibalo obuqhuba konke kusukela ezindleleni zeziphepho kuya emishinini yezimboni. Kulesi sihloko, uzohlola izinhlobo ezahlukene zemijikelezo, isayensi engemuva kobuhle bayo, nendlela emangalisayo esebenza ngayo emishinini yanamuhla yokucubungula amaminerali.

Izazi zezibalo nabaculi sebehlukanise imijikelezo (spirals) emakhulwini eminyaka, behlonza imindeni ehlukene elandelayo imithetho ethile yejometri. Uhlobo ngalunye lukhula ngendlela ehlukile, futhi leyo ndlela yokukhula inquma ubuhle bayo nokusebenza kwayo okungokoqobo. Ukuqonda lokhu kwehluka kubalulekile, ikakhulukazi konjiniyela abaklama imishini emijikelezayo yezimboni ezinkulu. Ngezansi, sihlola imindeni emine yakudala yemijikelezo ebaluleke kakhulu kwezobuciko nobunjiniyela. Njengoba sizobona, amajika afanayo ahlobisa imvelo nawo ashayela ukusebenza kahle kokuhlukaniswa ezimayini.

I-Archimedean spiral igcina ibanga elingaguquki phakathi kwemijikelezo yayo elandelanayo, njengemisele ekwi-vinyl record noma ipayipi lasegcekeni eligoqwe kahle. Ngenxa yokuthi isikhala asishintshi, le spiral ikhula ngezinga elizinzile, elingabikezeleka kalula ngokwezibalo. I-pitch yayo efanayo iyenza ibe usizo kakhulu ekusetshenzisweni kwemishini lapho ukunyakaza okungaguquki kudingeka khona kulo lonke umsebenzi. Ama-spiral classifier amaningi ezimayini ancike ku-Archimedean geometry ukuze athole ukuthuthwa kwezinto okufanayo nokugeleza okuzinzile. Lapho onjiniyela bekhuluma nge-spiral yangempela, bavame ukucabanga ngalolu hlobo lwe-constant-radius kuqala. Lokho kuthembeka yikho kanye okwenza kuhlale kuyithuluzi elibalulekile ekwakhiweni kwezimboni.

I-spiral ye-logarithmic ikhula ngezinga elikhula ngokuphindaphindayo, okusho ukuthi ijika ngalinye likhulu ngesilinganiso esingaguquki kunelangaphambi kwalo. Leli phethini lokuziphindaphinda litholakala kuyo yonke imvelo, kuhlanganise nemithala yemithala, iziphepho, namagobolondo amaningi ezilwane ezinamagobolondo. Isibonelo esidume kakhulu i-Golden Spiral, ekhula ngokwesilinganiso segolide esingaba ngu-1.618. Emakhulwini eminyaka, abaculi nabaklami bezakhiwo babekholelwa ukuthi lesi silinganiso sikhiqiza ukwakheka okuhle emidwebeni nasezakhiweni. Ucwaningo lwanamuhla selukufakazile lokho, njengoba izivivinyo eziqaphile zembula ukuthi abantu bathanda kakhulu i-Golden Spiral kunalezo ezisondelene nayo. Lobu buhle bemvelo yikho okwenza i-spiral ye-logarithmic ibe yisilinganiso sobuhle bokubukwa nokulinganisela okufanele.

I-Fibonacci spiral iwukulinganisa okusebenzayo kwe-Golden Spiral eyakhiwe ngokulandelana kwama-quarter circles. Iqala ngamaskwele anosayizi ohambisana nezinombolo ezidume zika-Fibonacci, i-arc ngayinye yekota ixhuma phakathi kwamaskwele aseduze ukuze kukhiqizwe umzila ogobile obukeka bushelelezi. Ngenxa yokuthi izinombolo zika-Fibonacci zivela kaningi ekukhuleni kwezitshalo, i-Fibonacci spiral ivame ukuvela ezinhlanhlathini zikabhekilanga, ezinkalweni zikaphayini, ngisho nasezikalweni zikaphanana. Kufanele kuqashelwe ukuthi i-Fibonacci spiral ayiyona i-logarithmic spiral yangempela, ngoba ukugoba kwayo kushintsha kancane emngceleni wengxenye ngayinye. Noma kunjalo, isondela kakhulu kwi-golden curve ekahle, yingakho ivame ukuphuthwa ngokuthi iyona yangempela. Nokho, lowo mehluko omncane ubalulekile lapho ukunemba kuba inhloso.

Kusenjalo, i-spiral ka-Dürer inikeza ukulinganisa okudala, okwenziwa ngesandla, kwe-spiral ka-Archimedean, edwetshwa umdwebi weRenaissance u-Albrecht Dürer esebenzisa imigqa eqondile nama-arc ayindilinga. Ngenxa yokuthi yadwetshwa ngokwejometri kunokuba ithathwe kufomula enembile, i-spiral ka-Dürer inokungapheleli okuncane ekugobekeni kwayo. Lokhu kungahambi kahle okuncane kungabukeka kukhangayo emfanekisweni oqoshiwe, kodwa kubaluleke kakhulu ezinhlelweni zobunjiniyela obunembile. Ukuqhathanisa phakathi kokulinganisa kuka-Dürer ne-spiral yangempela ka-Archimedean kunikeza isifundo esiwusizo: ukunemba ekugobekeni kunquma ukusebenza kahle ekusebenzeni. Leso sifundo sidlulela ngqo ezimweni zezimboni, lapho umehluko omncane wejometri ungashintsha kahle ukusebenza kwemishini. Nokwehluka okuncane kokuma kungahumushela ekulahlekelweni kwamandla okukhulu ngezinga elikhulu.

Kungani abantu bethola imiphethu (spirals) ikhanga kangaka ekuqaleni? Ucwaningo lwanamuhla olwaqhathanisa ngokuhlelekile ukuthandwa kwababukeli phakathi kwe-Golden ne-Fibonacci spirals lwanikeza izimpendulo ezibalulekile. Kulolo cwaningo, iphesenti elimangalisayo elingu-79.2% lababambiqhaza bakhetha i-Golden Spiral kunenguqulo ye-Fibonacci, okusikisela ukuthi amehlo ethu ayakwazi ukubona umehluko omncane wokugoba phakathi kwazo. Ngokufanayo, u-81.1% wababukeli bakhetha i-Archimedean spiral yangempela kunokulinganisa kuka-Dürer lapho becelwa ukuthi bahlule ubuhle obubonwayo. Abacwaningi baphetha ngokuthi ukugoba okuqhubekayo, lokho izazi zezibalo ezikubiza ngokuthi i-fair curve, yikho okungumgogodla wokubonakala kobuhle. Uma ukugoba kubushelelezi futhi kuqhubeka ngokufanayo, imiphethu ibonakala ithokozisa kakhulu emehlweni omuntu. Lokhu kutholakala kwesayensi kuxhumanisa ukuthakasela kobuhle ngqo nokunemba kwezibalo, umgomo obonakala ubaluleke ngokulinganayo ekwakhiweni kwezimboni nobunjiniyela.

Izimiso ezifanayo zejometri ezenza imisipha ibe yinhle nazo ziyenza isebenze ngendlela emangalisayo embonini enzima. Ekucubunguleni amaminerali, ukuhlukaniswa ngamandla adonsela phansi kusebenzisa iqiniso lokuthi izinhlayiya ezinobukhulu obuhlukile zihamba ngendlela ehlukile emgudwini ogobile. Imishini efana nama-spiral classifier nama-spiral concentrator isebenzisa umgudu oyindilinga ukuhlukanisa i-ore ebalulekile kudoti nokungaguquguquki okumangalisayo. Njengoba i-slurry igeleza yehla nge-spiral, amandla e-centrifugal aphusha izinhlayiya ezisindayo ziphume zibheke ngaphandle kanti izinhlayiya ezilula zikhukhulela emaphethelweni angaphakathi omgudu. Ukugoba okuthile kwe-spiral kunquma ukuthi lezo zinto zihlukana kahle kangakanani, yingakho i-geometry ibaluleke kakhulu ekusebenzeni kahle kokuthola amaminerali. I-spiral eklanywe kahle ingathola amaminerali abalulekile ngamandla amancane, okuyenza ibe ukukhetha okuhle emvelweni emisebenzini yezimayini yanamuhla. Yingakho abasebenzi abaningi sebefake izinto ezintsha esikhundleni sobuchwepheshe bakudala ngama-gravity spiral chutes ahlinzeka ngama-concentrates ahlanzekile ngezindleko eziphansi.
